That being said, the ED approach here does have some advantages over the GQTs considered in the non-relativistic regime. As demonstrated by Bialynicki-Birula and Mycielski [1]} in the context non-relativistic quantum mechanics, for instance, one possible nonlinear generalization to the usual Schrödinger equation, which satisfies certain requirements, is given (up to an overall additive constant) by
\(F[\rho ] = \int dx \rho \log \rho ~,\)
